The kernel unconditionally forces an exact match on VLAN TCI\nwhen parsing flow keys, and requires both OVS_KEY_ATTR_VLAN and\nOVS_KEY_ATTR_ENCAP for VLAN frame validation. Without vlan()/encap()\nparsing, no VLAN flow match is possible from ovs-dpctl.py.\n\nPatch 1 fixes two pre-existing nla_map type bugs: OVS_KEY_ATTR_VLAN\nwas mapped to \"uint16\" instead of the correct big-endian \"be16\", and\nOVS_KEY_ATTR_ENCAP was mapped to \"none\" instead of \"nested\". It then\nadds the vlan() and encap() flow string parsers, dpstr() display\nsupport, and proper ovskey instance returns for encap.\n\nPatch 2 adds a test that uses kernel VLAN sub-interfaces to generate\n802.1Q tagged frames and verifies pop_vlan via pcap at the egress\nveth. A negative check confirms tagged frames arrive intact without\npop_vlan, then the positive check confirms the tag is stripped.\n\nNo regression in the existing OVS selftests.\n\nSigned-off-by: Minxi Hou <houminxi@gmail.com>\n---\nv1 -> v2: rebase to latest net-next/main, drop --base=auto\n\nv1: https://lore.kernel.org/netdev/20260501122756.3081754-1-houminxi@gmail.com/\n\nMinxi Hou (2):\n selftests: openvswitch: add vlan() and encap() flow string parsing\n selftests: openvswitch: add pop_vlan test\n\n .../selftests/net/openvswitch/openvswitch.sh | 132 ++++++++++++\n .../selftests/net/openvswitch/ovs-dpctl.py | 190 +++++++++++++++++-\n 2 files changed, 320 insertions(+), 2 deletions(-)" }
